Model Rocket Launcher

The original model is RC Plane Launcher by quadcells - Thingiverse, and I utilized all parts except for the gantry_plate and pedel_swivel. My rendition omits any components from the original; you must download them from the original model's website. To circumvent drilling into the 2020 profiles, I implemented an M5 bolt and T-nut solution.

The design excludes the aircraft securing mechanism; this requires custom fabrication based on your specific aircraft.

A separate print configuration provides a fixture compatible with Titan Hammerhead and Titan Micro Claw.

Several crucial aspects warrant attention during construction:

1. The front_2020_connector necessitates 100% infill to prevent breakage from the carriage. If minimizing material usage is preferred, ensure at least 2cm from the impact block receives 100% infill. Consider employing a minimum of 20% gyroid infill overall, with 50% recommended.
2. The latch requires a high-tension spring to secure the carriage. An outer diameter of 9-10mm is suitable, with a thicker wire gauge preferable. The length ideally should not be less than 25mm; if the carriage remains unsecured, consider a 30mm spring or combining multiple springs. A TPU spring model is included in the split files, serving as an alternative.
3. My design utilizes 2050 rubber bands. If insufficient force is observed, consider 3060 rubber bands. The rubber band retainer is adjustable; positioning it at the base of the front support leg extends the band's travel. A 50% gyroid infill is recommended for this retainer.
